Heat and interference question

I purchased the below products. They will both be running off of a 24v, 20amp supply.

I want to mount them to a 1/8" acrylic panel on brass stand offs. What type of temperature should I expect from them? What height of standoff would you recommend? What distance would you recommend they be from the Raspberry Pi and Jrk controllers? Would they generate any interference with PWM to the Jrk controllers?

D24V50F5 (https://www.pololu.com/product/2851) constant 3amp draw.
and
D24V150F12 (https://www.pololu.com/product/2885) periodic 2 minute duration 9 amp draw.

Thanks in advance,
D.

Hello.

It should be fine to power the Jrk controller from a regulator; however, we have not characterized the temperature of our regulators as a function of the current draw. As far as distance to your other components, we generally recommend keeping wire lengths between components as short as possible.
